PLA2002D + 10 wt% 100Ag-LMT Film

A solution of PLA2002D and 100Ag-LMT, made on 2013/03/05 was cast into a Teflon dish. Please refer to the entry on 2013/02/06 for the protocol.

ISE Study of PLA2002D + 5 wt% LMT

From a 3 g film of PLA2002D + 5 wt% LMT, made on 2013/02/19, three 0.5 g samples were cut with scissors. Each sample was placed in a 100-mL polypropylene beaker filled with 50 mL pure H2O and 1 mL of ionic strength adjuster (ISA). The control was a solution consisting of 50 mL pure H2O and 1 mL of ISA without a film in a polypropylene beaker.

The conductivity of each solution was measured with an Accumet silver/sulfide ISE every 30 min for a period of 2 h, then again after about 24 h.
